Description

The invention relates to a windshield according to the preamble of claim 1 and a connector device with such a claim 8.

Windshields serve in particular the protection of connectors between lines from wind and cold associated therewith. Plug connections form a pluggable connection between two conductor sections. The conductor sections may be electrical conductors or else hydraulic conductors. Often, for example, in electrical engineering, electrical conductors and hydraulic conductors are combined in a ladder tree. Among other things, this affects the wiper water pipes, which are integrated in cable harnesses.

The connectors are particularly susceptible to cold and there may be a freezing of the fluid in the hydraulic lines. Conduit connectors of electrical conductor sections generally have hard materials and can produce clattering and knocking noises when vibrated by colliding with other line connectors or peripheral components. For ease of maintenance, however, can not be dispensed with the line connector.

As windshields come in the art, especially in vehicle windshields used. These flexible windshields are pushed over the cable connectors, which they usually have to be postponed before with open line connectors on one of the conductor sections to be connected. The disadvantage of this is that they can only badly position electrical cables including the cable connectors and also hydraulic cable connectors. There is a risk that this will cause noise, e.g. Rattling noises. In addition, windshields are partially on the line connector, creating thermal bridges are formed. Fluids in hydraulic connectors can thereby freeze or at least become very viscous.

Another disadvantage is the uncontrolled mounting. First, the windshield is roughly brought into position and then usually a cable tie tightened around the ends. The tightening torque is hardly predictable, so either air passages remain free or conductors are squeezed. Depending on how ladder bundles just fall, the connection can loosen up later and slip the windshield. During assembly / disassembly, the hose ends should also be everted, which requires manual skill and time. In the case of maintenance is disadvantageous that the windshield hose must be pushed back to get to the individual line connector.

An alternative protection of at least one electrical connector is disclosed US Pat. No. 7,307,219 B1 in which two half-shells are used, which together form a shell with an internal cavity. The openings of the half-shells are each covered with an elastomeric membrane. When the electrical connector is now placed between and closes the shells, the two diaphragms deform around the electrical connector. The disadvantage is that a relatively large box is necessary around the electrical connector in order to realize this. If you put several cable connectors between the membranes, these in turn can collide with each other and are not properly positioned to each other. Furthermore, the membranes represent thermal bridges, which lead from the housing shell directly to the electrical connector. For multiple conduit connectors or hydraulic connectors, the sheath retracts US Pat. No. 7,307,219 B1 therefore rather unsuitable.

Furthermore, it is off GB 1 413 650 A a shell consisting of two half-shells known. The two half shells exactly follow the geometry of the male electrical conductors and connectors. The half-shells are placed around this and then connected to a flange by screws. The disadvantage is that a large thermal bridge is present, so that this training at low temperatures is not suitable for hydraulic line connector.

The object is therefore to provide a device which is suitable for preventing noise developments in the area of line connectors and for protecting hydraulic line connectors from low temperatures. In addition, it should be compact, easy and correct to install, easy to maintain and inexpensive.

Main features of the invention are set forth in claim 1 and claim 8. Embodiments are the subject of claims 2 to 7 and 9 to 13.

The invention relates to a draft shield having a plastic shell, which has a first part shell and a second part shell, wherein the first part shell and the second part shell enclose a receiving space and form a first and second conduit opening, which connect the receiving space with the surrounding area outside of the receiving space. In addition, the plastic shell has a holding means with a Recording geometry for at least one line connector, which is arranged on the first sub-shell and is formed so that a recorded with the receiving geometry line connector is held in the receiving space by an air gap spaced from the first sub-shell and the second sub-shell.

The advantage of such a design is the substitutability of wind protection hoses. It is a pre-assembly on one side or in a partial shell possible, which is easy to handle. It is achieved a permanent and accurate positioning of the cable connector in the windshield. The distance forms an air cushion around the connector contour, which is thermally insulated. In addition, rattling noises are prevented because the cable connector is in a defined position of the receiving geometry and can not collide with other components.

In a preferred low-cost embodiment, the holding means is integrally formed, in particular monolithic, with the first sub-shell. A simple and quick installation succeeds in particular, according to an optional embodiment, in which the first and second conduit opening are arranged in the parting plane between the first and second sub-shell.

Incidentally, the first and second subshells should follow the outer contour of the line connector (s). Ideally, a windshield, which has two slender ends with the conductor openings and an intermediate thickening in at least one spatial direction. Preferably, the maximum thickening is in the plane of the parting plane. This facilitates assembly by inserting the cable connector or connectors.

According to a further embodiment of the windshield, the first and second subshells are coupled to each other via a hinge, so that the first and second subshells are hinged and hinged relative to each other. This allows a simple and ergonomic handling. A cost effective variant is achieved when the hinge is a film hinge.

According to a special embodiment of the windshield, the retaining means is formed by a rib. The rib also stiffens the shells and prevents their deformation. The rib preferably extends transversely to the orientation of the line connector. The ribs can then initiate tensile forces on the conduit connector into the plastic shell.

Furthermore, the windshield can optionally have operable locking means with which the first and second sub-shell are closed together to form the receiving space. It is thereby possible a tool-free installation. Depending on the design, tool-based or tool-free disassembly can be realized. Preferably, the locking means comprise first locking means on the first sub-shell and second locking means on the second sub-shell. Inexpensive in the production, it is especially if the first locking means are integrally formed, in particular monolithic, with the first sub-shell, and the second locking means are integrally formed, in particular monolithic, with the second sub-shell.

An addition to the windshield can be that the receiving geometry has a first insertion means. Plugging the lead connector results in clear positioning and is easy to do from a single direction. The mounting facilitating insertion bevels are preferably provided on the first plug-in means or the counterpart.

In a variant of the windshield, a seal between the first sub-shell and the second sub-shell is formed and / or arranged. This is achieved by mechanically abutting sealing surfaces or by an elastic seal. Thus, no wind penetrates into the windshield. Also in the region of the conduit openings seals may be provided, in particular elastic sealing sleeves.

Furthermore, a further embodiment of the windshield cover provides for a hold-down to be arranged on the second subshell and to be configured so that a line connector accommodated with the receiving geometry is held in the receiving geometry when the receiving space is closed by the first and second subshells. By closing the plastic shell, the cable connector is thereby held securely in position, after it could be pre-assembled in the first part shell quickly by inserting. It is cost-effective if the hold-down is integrally formed, in particular monolithic, with the second partial shell. A high stiffness of the windshield is achieved when the hold-down is formed by a rib.

A special embodiment for cold application areas is supplemented by the fact that an electrically operated heating element is arranged in the receiving space. This is preferably operated as antifreeze heater in relation to the present in the line connector fluid.

In order to determine the windshield correctly and permanently at a certain place, it is advisable to supplement them so that the Plastic shell has a fastening means for fixing to another component. This fastening means may be, for example, a clip contour, a latching means or a tab with an opening.

The invention also relates to a connector device with a windshield in one of the variants described above, wherein a cable connector is received in the receiving geometry. This subject of the invention is also suitable for providing a sound-absorbing and insulating receptacle of a line connector, wherein the plug connection device is inexpensive and easy to handle.

In a further embodiment of the plug-in connection device, the receiving geometry has a first plug-in means and the line plug connector has a second plug-in means, wherein the first and second plug-in means form a mechanical plug connection. An insertion of the line connector is quick to carry out and it is achieved a clear positioning.

In a nähr embodiment, the line connector forms a plug connection between a first and a second conductor section, wherein the first conductor section are guided through the first conduit opening and the second conductor section through the second conduit opening out of the receiving space in the surrounding area. The plug connection device is particularly suitable if the first and second conductor sections are electrical conductor sections and / or hydraulic conductor sections.

In a particular variant of the plug connection device, the line connector connects two hydraulic conductor sections to one another, and a second line plug connector is arranged, in particular, at an air gap spaced from the first line plug connector in the receiving space. Thus, not only several cable connectors are space-saving housed in the same windshield, but the hydraulic line connector thermally insulated from the second line connector by an air cushion.

In a preferred embodiment of the connector device, the air gap around the line connector is substantially uniform. Thus, the thermal insulation is homogeneous in all directions.
